At the upper edge of the shortened the edges 35 of blades 34, inFig.-'1, as

would be necessary to correctly portray these edges as seen in Fig. 3.

Closely surrounding barrel is an enclosing shell 36, partly cylindricalin contour, but extending at one side, as at 31, to house the auxiliarydriving shaft 38, this shaft being journaled in two spiders 39 and 40,the former of which is fast within the upper end of a movable cylinder4|, and the latter being fast within a stationary auxiliary cylinder 42,this last being fast to the shell extension 31. The movable cylinder 4|rests on a pin 43 which is fast with auxiliary cylinder 42, but pin 43has also another function which will be later described.

My machine is provided withlegs 44 which may be secured to barrel 215 orshell 36, as desired, and it is to be understood that I may mount legs44 -on rollers or castors Hi8, withoutdeparting from the spirit of myinvention. The driving mechanism will now be described. Beneathbarrel.25, and preferably mounted on legs 44, is a motor M with an upwardlyextending shaft 45 at whose upper end is fastened a driving pulley 46.On the lower end of auxiliary shaft 38, is fast a second drive pulley41, pulleys 46 and 41 being connected by the rope or belt drive 48. 7 Atthe upper end of auxiliary shaft 38 is fast a third drive pulley 49which, by a second rope or belt drive 50, is connected to a fourth drivepulley 5|, this last being splined on drive-shaft 20, as seen at 52. Astud 53 in fourth drive pulley 5| is adapted to engage the key-slot 52on driveshaft-2ll, and, being removable, pulley 5| becomes loose onshaft 20 when it is desired to dis-assemble the machine. The precedingword loose has a relative meaning,. as pulley 5| is adapted to snuglyengage shaft 26 so as to cause-suflicient friction to hold shaft 20 inraised position, as will be later described. g

Within block 22, and surrounding shaft 20, is a sliding bar 54, providedwith a handle 55, and also with an enlarged opening 56, this openingbeing adapted to register with the collars of ballbearing 2|, in awell-known manner. See Fig. 2. Opposite block 22, and fast-on cover 23,I preferably mount a switch-box 51 with which bar 54 operativelyconnects when it is desired to operate my machine. This position isshown'in Figs. 1 and 2. When bar 54 is withdrawn the circuit is brokenin switch-box 51 and motor M becomes idle.

Ball-bearing 2| comprises: a collar 58 fast on shaft 20 and a secondcollar 59 loose thereon. With bar 54 in the position shown, the upwardthrust of the water, before referred to, causes collar 59 to impingeagainst the underside of bar 54 as an abutment. Being free on shaft 20,this friction causes collar 59 to remain stationary while the machine isin operation,- thus callin ball-bearing 2| into play. i

From the foregoing description, it will be seen that when motor Moperates, lugs l9 on driveshaft 20, by engaging socket I8 on flangecause lid I3 to revolve in clock-wise direction and, through the agencyof lugs l5, which are formed integral with drum the drum, with itscentral tower 6 and turbine 5 also are rotated. The garments to becleaned are packed within drum and around tower 6, and the action ofturbine 5 sets up a whirling motion of the liquid in well l0 which iscaught by the blades 34 and concentrated directly beneath tower 6. Asthe speedof the motor increases, this concentration produces a pressurewhich forces the liquid upward within tower 6 until it has reached thetop thereof,

1 speed of the motor.

whence, by centrifugal action, the liquid, finely comminuted by thescreen 8, passes through the perforations l and through the garments G,after which it escapes through perforations 2 in the sidewall of drumand falls upon the stationary vanes 26, the contour of which accentuatesthe whirling efficiency of turbine 5.

Thus it will be noticed that, during the entire washing operation,clothes G are held stationary withindrum I, being pressed against theouter wall thereof by centrifugal action and thus leaving a very smallspace immediately surrounding tower 6, the amount of this spacedepending partly upon 'the tightness with which the garments have beenpacked, and partly upon the The liquid which emerges from tower 6 in theform of a fine spray or mist is driven through the clothes bycentrifugal force, thus searching out every part and hidden foldthereof. The height to which the liquidcan be forced in tower 6 dependspartly upon the speed of motor M, but mainly upon the fineness of themesh of. screen 8. 1

At the completion of the cleaning operation, it becomes necessary todraw. the cleaning fluid from the machine and replace it with cleanwater for rinsing purposes. To accomplish this, I employa pump connectedwith a flexible hose H, by means of which the liquid may be draineddirectly into a sink-tray or set-tub which may be located in closecontiguity with my machine.

The draining mechanism will now be described in detail.

Pedestal 28 is provided with a plurality of drain openings 60 throughwhich the liquid may freely and fully escape. Openings 69 register witha verticallyarranged and partly hollowed bolt 6|, the upper end of whichis fast with floor 21 of barrel 25. The free end of bolt 6| is housed ina closedbox 62, and its hollowed portion is provided withperforations63. Also, to box 62, but

at one side, I make fast a short nipple 64, to

.whichhooks over the edge of the tray. This hook is adjustably securedon hose H, and when the washing operation is under way, hose H may besuspended against the side of the machine by placing hook 65 over thebracket 66, secured to shell 36. A sto-pcock 61 may be inserted in theline of hose .I -I at any convenient point. Directly above nipple 64 isa vertically arranged shaft 68, journaled in box 62'. Fast upon thelower end of shaft 68 is a turbine wheel 69, housed in a turbine-well10; Fast at the upper end of shaft 68 is a drive pulley 1| so positionedas to be within the sphere of action of rope drive 48.

Exteriorly connected to the freeend of box 62' is an arm-l2 which ispivotally connected at 13 to a partly hollow tube." (see Fig. 5). Withintube 14 is a plunger rod 15 which is pivotally connected at 16 to arock-arm '11, the latter being pivotally mounted at .18 to the shell 36.The free end of rock-arm H is so shaped as to be readily grasv'd by thehand of the operator. Ordinarily, pulley II is out of commission, itbeing positionedmidway between the two strands of rope-drive 48,. asshown in Fig. 3. When it is desired to start the pump, rock-arm 11 isthrown from the full position seen in Fig. 3 to the dash been thrownbeyond dead center. In this'operation, plunger 15 compresses spring 19within tube 14, andlin the thrown position, the thrust of spring 19keeps pulley H in operativecontact with one strand of rope-drive 48. Asthe motor M is running, the turbine wheel 89 is operated to expel theliquid through hose H, being assisted by the centrifugal force ofturbine 5. After draining off the washing fluid, motor M is stopped andhose H is attached to the water faucet o'rdinarily found withinsink-trays, whereupon the pressure behind the faucet will force cleanwater back through hose Hand into water-well l0. When a suflicientamount of water is'assembled within the machine, hose H is disconnected,stopcock 61 is shut off, rock-arm I1 is reversed to free pulley H andmotor Mis again started by pushing bar 54 back into switch-box 51 or,pref-' erably by closing auxiliary switch 88. Again the whirling motionis set up and the clean water, delivered in the form of spray or mist,through screen 8, is driven through the clothes G, thus searching outand eliminating all traces of the cleaning fluid from the clothes.

After draining off the rinsing water'by repeat ing the former operationsfor the cleaning fluid, the positions of the parts as seenin' thedrawings are restored and again the motor is set in opera-' tion. Onthis occasion, what water remains in the clothes is forced out throughperforations 2, and none entering from tower 6, the clothes arepartially dried, as is customary in wringing methods.

From the above description, it will be clearly seen that, oncepackedwithin drum the clothes are not disturbed until after the rinsingand wringing operations are completed, thus saving all wear and tearupon the garments.

As a support for cylinder 24, Iprovide one or more set-screws I09 whichpass through shell 36 and barrel 25.

The method of packing and unpacking the clothes will now be described.Referring to Figs. 2 and 3, it will be noticedthat the auxiliarydrive-shaft 38 may be termed thepivot around which the cover 23 may beswung until the lid l3 is fully exposed. With the cover will move the,

drive-shaft 28 with all its mountings, but first, drive-shaft 20 must bedisengaged from lid l3. The method of procedure is as follows: At theupper extremity of drive-shaft 20, I mount a hand-wheel which is soconstructed that, while the machine is in operation, the operator couldgrasp wheel 80 and hold it against rotation with shaft 20; but if themachine is idle, wheel 80 may not be turned in clock-wise directionwithout rotating shaft 20. This check or ratchetprevent horizontalmovement of cover 23.

To remove or swing cover 23, handle 55 of bar 54 is grasped and pulledlongitudinally until opening 56 registers with collar 59. This stopsmotor M. Incidentally, it might be noted that an auxiliary switch, as88, may be inserted in the circuit 89 that connects switch-box 51 withmotor bingthat otherwise would occur.

The spring fastening 84 is adapted to register with the opening 8'!in.1ever,85 and thus- M,'*in case it desired to leave bar 54inillustrated position when the machine is not in use.

To continue,the second step in the operation is to grasp hand-wheel 80and raise it and, with it,

shaft 20. against the friction caused by. the close sliding fit thereonf of drive-pulley 5|. When shaft. 28. is in raised position, the. collar59.is within andeven partly above opening 56 of bar 54, andfthe lugs l9are disengaged-from the lever 85 and cover '23is swung clock-wise untillid I 3. is completely uncovered; As cover 23.

swings, movableicylinder 4| swingswith it, said cylinder being heldfastinthe grip of a fork'9l which-forms part of thelgrid 92 V i thatprovides a bearing '83'. for shaft20 g This and other fasteningsreferred to throughout this specification,unlessrotherwise illustrated,are formedby. brazing or soldering theparts together, although it is tobe understood thatI may employ bolts or other detachable fasteningswithout departing from the spirit of my invention.

As cylinder 4| rotates; the cam surface 94,

formed on the lower edge of said cylinder, rides on the pin 43 andcauses cover 23 to lift as. it

swings, thus avoiding the sliding friction or rub- With cover, 23 aside,lid l3 may be removed graphing handles 95, 95 and raising to free lugs]5, from the openings, 5. After .the clothes are packed within drum I,theabove operations are reversed to restore the illustrated conditions.Also, the same operations are repeated when it is desired toremove'theclothes.

A plug 96 conceals an opening 91 in block 22,-

this opening being necessary toinsert the setscrew 98 that fastenscollar 58 on'shaft 20. Among the miscellaneous parts which enter intothe construction of my machine maybe mentioned a a series of woodbushings 99, 99 which are inserted into a number of the bearings toavoidthe necessity of oiling; a'ball-bearing lull inside the pump;lock-nuts I01 for bolt 6i; wooden gaskets I02 around bolt 6| the channelbar I03 upon which motor M and bearing 45 are mounted; the collar I84which surrounds the upper end of bolt 6| and is fast, to the under sideof floor 21 of barrel 25;

and the pin I I0 which formsa'sto'p to prevent the I complete removal ofbar 54...

The stationary vanes 26 are, shown as formed f upon a ring I 86 .thatisbrazed or soldered within the lower rim of open-ended cylinder 24.Similarly, the vanes of turbine 5 are formed on a ring I01 that isbrazed or soldered onjth'e outside of the lower edge of the dependingwall 4 that is connected with drum I.

By an inspection of Fig. 3, itwill be noted that vanes 26 are soconstructed as to leave a suitable clearance around'wall4.-.'.Similarly, the vanes of turbine 5'are so constructed as toprovide'a suitable clearance within the side wall of barrel 25. 1 Toremove drum l for inspection or repair, setscrews I09, but one of whichis shown, are removed and cylinder 24, with its vanes 26 may be liftedout, after which drum' I may be removed. 7 Having described myinvention, whatI claim is:
